Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is derived from the lead wire connected to the armature coil of a magnet generator and a separate part. A magnet that fixes the wire harness made by bundling the lead wires together to the armature core. The present invention relates to a wire harness fixing device for a generator.

0002

[Conventional technology]

In magnet generators attached to internal combustion engines, the Connected to multiple leads and cords derived from other components such as signal generators Bundle the lead wires to form a wire harness, and lead the wire harness to the outside. ing. In order to prevent lead wires from breaking or coming into contact with the magnet rotor, The base must be fixed to the armature core.

0003 Figure 7 shows the structure near the wire harness fixing device of a conventional magnet generator for internal combustion engines. 1 is a schematic diagram showing an armature core 100 and a bobbin 101 attached to the core. shows the armature of a magnet generator with an armature coil 102 wound through There is. A magnet rotor (not shown) is arranged on the outer peripheral side of the armature core 100, and the magnet The magnetic poles of the rotor are opposed to the armature core 100 with a predetermined gap in between. child Lead wires 1a, 1b, 1c,... are drawn out from the armature coil of the magnet generator. ing.

0004 2 is for obtaining a signal to give information on the rotation angle of the engine to the ignition system for the internal combustion engine. For this purpose, a signal generator (not shown) placed on the outer circumference of the magnet rotor generates this signal. The child is a separate part from the armature of the magnet generator. For example, the signal generator 2 is connected to the iron core. A signal coil is equipped with a wound signal coil and a magnet that causes magnetic flux to flow through the iron core. A reluctor in which the magnetic pole part of an iron core wound with are placed opposite each other through a predetermined gap, and a change in magnetic flux is caused by a reluctor. A signal voltage is induced in the signal coil when the signal is applied.

[0005] Note that this type of signal generator uses a Hall element instead of a signal coil to generate the signal. A signal voltage is obtained by sensing changes in magnetic flux using a Hall element. There is also one.

[0006] 2a1 is pulled out from the signal generator 2 in order to take out the output of the signal generator 2 to the outside. The lead wire 2a2 is connected to this lead wire, and the lead wire 2a1 is connected to the lead wire 2a2. The connection portion with the lead wire 2a2 is covered and protected by a protective tube 2b. In this example, lead wires 2a1 and 2a2 constitute separate component side lead wire 2a. .

[0007] Lead wires 1a, 1b, ... pulled out from the armature coil of the magnet generator and signal generation The separate lead wire 2a drawn out from the electron is bundled with the insulating tube 3. These lead wires and the insulating tube 3 constitute a wire harness 4. has been done. Among the lead wires that make up the wire harness, pull out from the armature coil. The lead wires 1a, 1b, ... are introduced into the tube from the end of the tube 3. , the lead wire 2a on the separate component side connected to the signal generator is provided in the middle of the tube 3. The tube is introduced into the tube through the hole 3a.

[0008] The wire harness 4 is fixed to the armature 1 by a wire harness fixing device 5'. has been established. One end of the wire harness fixing device 5' is welded to the armature core 100. Or, the base 5a' fixed with rivets etc. and the base 5a' standing up from the other end side. The wire harness 4 has a raised clamp part 5b', and the wire harness 4 has a raised clamp part 5b'. It is fixed to the armature 1 in a clamped state by the portion 5b'.

[0009]

[Problem that the idea aims to solve]

As mentioned above, in the conventional wire harness fixing device, the insulating tube 3 Drill a hole 3a in the middle and insert the lead wire 2a of another component into the tube through this hole 3a. 3, so in order to introduce the lead wire 2a from another part into the tube. The problem is that the work is troublesome and the number of man-hours required to pull out the lead wires increases. there were.

0010 Also, a braided tube or a glass-filled tube can be used as the insulating tube 3. Although it may be necessary, in this case, it is extremely difficult to make a hole in the middle of the tube. It was extremely difficult.

[0011] To prevent the above problem from occurring, connect the lead wire 2a on the other component side. Connect the lead wires 1a, 1b, etc. on the armature coil side without passing through the hole 3a of the insulating tube. It is also conceivable to introduce both into the tube from the open end of the tube. but In this case, the lead wire 2a on the separate component side will be wired over a long distance. Therefore, the lead wire 2a may come into contact with the open end of the magnet rotor or the boss, causing a short circuit or disconnection. A problem arises in that accidents on lines, etc. are more likely to occur. Also, the lead wire on the other component side is equivalent. Because the lead wires are long, there is a risk that the lead wires on other parts may be shaken and broken due to engine vibration. was there.

0012 The purpose of this invention is to connect the lead wire drawn out from the armature coil and the armature coil. A wire harness is formed by bundling together the lead wires on the side of another component that connect to another component. without drilling holes in the insulating tube that protects the wire harness. In addition, the lead wire on the other component side can be connected without causing accidents such as breakage of the lead wire on the other component side. Insert the lead wire into the insulating tube together with the armature side lead wire and connect it to the wire harness. A wire harness fixing device that allows the wire harness to be fixed to the armature core. Our goal is to provide the following.

[0013]

[Means to solve the problem]

This invention connects the armature coil side lead wire connected to the armature coil of a magnet generator. , the armature coil and the separate component side lead wire 2a connected to the separate component 2 are bundled and insulated. A wire harness 4 covered with a tube 3 is attached to an armature core 100 of a magnet generator. This relates to a wire harness fixing device for a magnet generator.

[0014] In the present invention, the locking portions 510 and 512 that engage with each other form the opposing shapes. A clamp tool 500 having a pair of clamp pieces 503 and 505 that are connected in a state is used. This clamp tool is then fixed to the armature core 100.

[0015] The pair of clamp pieces 503 and 505 are made of insulating material and are 4 and the wire of the separate component side lead wire 2a. and second clamp parts 508 and 509 that clamp parts located outside the harness. It has an integrated structure.

In addition, the part of the lead wire derived from another component located outside the wire harness is It can be clamped using the clamp section.

[0017] Therefore, it is necessary to make a hole in the insulation tube covering the wire harness and bundle it. There is no need for assembly, and the number of assembly steps can be reduced.

[0018] In addition, if a clamp made of insulating material is used as described above, the lead wire on another component If there is a connection part in the middle, the insulating tube covering the connection part can be omitted. Therefore, the number of parts can be reduced.

[0019] Furthermore, as shown above, click the part of the lead wire on the other component side that is located outside the wire harness. If the lamp is turned on, the lead wires on other parts may be shaken due to vibrations of the internal combustion engine, causing breakage, etc. It is possible to eliminate the risk of accidents occurring.
